According to our knowledge, the tissue-specific short peptides connect to the exactly determined parts of the proper genes opening this way the DNA molecules and obtaining the information they contain. With the advance of time the organism is more and more lacking of peptides and this accelerates the deterioration of the tissues and the aging of the organism. The essence is that the proper functioning of the tissues requires an adequate amount of peptides, which are responsible for optimizing the functioning of the genes. The peptides present in the different cells synthesize also there. With the advance of life the cell functions split causing split in the reproduction of the peptides as well and this causes further damage to the cell functions. The degeneration of the tissues intensifies and this means clinical case. Hence, the use of short peptides is one of the best possibilities to significantly slow the aging process due to the stimulation, proliferation and regeneration of the tissue as well as to the increase in the number of cells. Another important advantage of peptides is due to its significant anti-tumor effect. For the moment, the use of peptides is the best solution without compromise for the prevention of cancer and for the recovery, because it allows the renewal of cells and tissues. This can be obtained not only by the regulation and coordination of the cyclical processes, but also by the strengthening of the cell division without the risk of anomalies, suitable for tissue reconstruction.
